Real case scenario: Migration of the Web Catalog Security in OBIEE 11g

.

I’ve recently been assigned to a customer project where I was in charge of the BI System Administration. The project was in the user acceptance stage and changes to reports & dashboards happened very frequently.

One of my daily tasks involved moving the latest web catalog changes from a development instance (where the latest user requirements were covered) to the user testing environment.

To mention that security played a very important role during these migrations since the web catalog privileges had to remain untouched within the target environment.

Secured Oracle HTTP Server: Configuring SSL

.

In a previous post we explained how an Enterprise OBIEE 11g environment can be secured when deploying OBIEE 11g content outside the organization by placing an Oracle HTTP Server (OHS) into the DMZ side firewall. In this new post we will describe the steps needed to configure the OHS to redirect traffic from outside the DeMilitarized Zone (DMZ) using a secured HTTP communication with Secure Sockets Layer (SSL).

The following graph describes the environment:

Big Data Strategy

.

As dust begins to settle, the hype around Big Data is slowly changing into a more realistic thinking on how to actually make it work. At this point, mostly everyone have heard of Big Data and have a clear understanding of what it is and what could be the benefits of putting in place a Big Data strategy in the company. However, one of the main adoption barriers is still the technical complexity when it comes to envision and deploy a Big Data solution.

These kinds of projects are usually driven by IT and the CIO on the early stages. The key at this point is to identify a use case to prove that the investment on a Big Data project is worthy; this use case has to clearly demonstrate that thanks to the new data analysis strategy new unprecedented insights could be unleashed allowing for game changer decisions to the company.

For many companies this is just the easy part, many CIOs were conscious already of the huge value that the data produced had, and yet they were not able to bring that data in their BI systems due to its size, speed, lack of structure, etc… Now, Big Data seems to make that possible, but the question that remains is: How are we going to do it?

How to secure an Enterprise OBIEE 11g environment: the Oracle HTTP Server

.

Most clients have their Oracle Business Intelligence Enterprise Edition (OBIEE) 11g environment inside their Local Area Network (LAN) secured behind two firewalls, one between the World Wide Web (WWW) and the DeMilitarized Zone (DMZ) and another one between the DMZ and their LAN as it can be seen in the following graph.

OBIEE Metadata Dictionary in 11g

.

As seen in one of our previous blog articles “Step-by-step on how to generate a Metadata Dictionary”, sometimes you might need to make accessible to the users information about metrics or attributes from repository objects. It’s useful to check quickly this information when you’re developing or creating a report using only a web browser or when you don’t have permissions to access the repository.

A metadata dictionary is a static set of XML documents where each XML document describes a metadata object with its properties and relationships with other metadata objects. The metadata dictionary has to be generated each time repository changes are made.

In this article you’ll find a step-by-step guide to generate a Metadata Dictionary in OBIEE 11g. Continue reading this post >
